The short answer
Most refrigerator noise complaints on compact cabinets of this kind are not failures at all. These units sit in tight spaces, often against cabinetry, and they transmit ordinary compressor vibration into whatever they touch. Separate that from the sounds that matter: a fan ticking against ice, a relay clicking without a start, and a grinding that changes with the door. The WUF family as the table shows it is one model number. Work from the full number on the rating plate rather than from the family letters when you order anything.
What you actually observe
- Buzzing or rattling from the back when running — Vibration transmitted into a panel, a pipe or the wall. Cheap, common, and usually fixable in minutes.
- Ticking or chirping from inside the cabinet — A fan blade catching ice or debris. This one affects cooling and should not be left.
- Clicking every few minutes with no cooling — A start relay trying and failing. Stop and call before the compressor is damaged.
- Gurgling or trickling after the compressor stops — Refrigerant settling and defrost water running. Normal on every unit of this type.
- NEAR MISS — a hum that has always been there — Compact cabinets are audible by nature, particularly in a quiet room. A long-standing hum is not a fault.
Where the noise usually comes from
- The installation rather than the appliance — Ranked first on this family: a cabinet in a recess, against a wall, or standing on a floor that is not flat. Nothing has failed and everything is audible.
- Frost against a fan blade — Second, and the reason a noise complaint often becomes a defrost diagnosis. A tick or chirp from inside is a blade in contact with ice.
- Contents, shelves and trays — Third. Bottles touching, a shelf half-seated, a drip tray displaced by a move — all convincingly mechanical and all free to fix.
- Mounts, relay and compressor — Last. Clicking with no cooling is urgent; a deepening hum with poor cooling is a cooling fault; tired mounts are noise alone.
Check in this order, and why that order
- Note whether it is constant or cyclic — A noise that follows the compressor cycle is mechanical; a noise that appears once every several hours is usually the defrost system.
- Press-test the panels while it runs — Gentle pressure at the sides and back. A rattle that stops under your hand is resonance and needs packing or levelling, not parts.
- Pull the unit out and listen again — Noise that halves when the cabinet is away from the wall was never a fault in the first place.
- Escalate anything metallic or new — A fan bearing, a compressor mount or a relay. All are behind panels on a live cabinet, so that is where owner work ends.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. Levelling the cabinet, checking clearance, reseating a drip tray and listening at the door need no panel off at all. Do not put your hand into a compressor compartment or near a fan blade on a running unit, and treat moving a full cabinet as a two-person job rather than a shove.

Where the owner line is on these models
Stop and call if the unit clicks every few minutes without cooling, if the sound is a grind rather than a rattle, or if a fan is audibly catching. Otherwise work through levelling, clearance, the drip tray and an empty-cabinet test, and be honest about the sounds that are normal on a small sealed system: gurgling, trickling, popping and a hum that is simply audible in a quiet room. Because the WUF line is a single model number, a technician can look the parts up before arriving, which is worth mentioning when you call.
